Research Subject

Design of novel electrode and electrolyte materials for fuel cells and electrolysis applications

研究の背景 Background

Further development of fuel cell technology requires enhancement of several important properties including higher catalytic activity of electrode materials, greater stability under operating conditions and lower cost of constituent parts. Additionally, hydrogen production via water electrolysis also requires higher stability of materials, employed for design of solid alkaline water electrolysis cells. Experimental development of fuel cells and hydrogen production is expected to be complimented by computational modeling within this project.

研究の目標 Outcome

This work aims at computational search for novel cathode structures (e.g. Pt-containing alloys), featured by a higher activity as compared to conventional pure Pt structures, higher stability, caused by the absence of carbon support, easily corroded under operating conditions and lower cost (due to alloying with less expensive metals). Also, effects of flourination on the design of stable membranes, used in water electrolysis will be studied computationally.
